What problem does it solve? Turning a rough feature idea into a structured, reviewable Product Requirements Document is slow and inconsistent when done ad hoc. This Skill runs stage 1 of the SDD pipeline, producing a standardized PRD at specs/<slug>/prd.md with sequential numbering, optional UI wireframes, and timing logs. ## Core Features & Use Cases - PRD Generation: Invokes the product-design agent to write a PRD from a free-text request or an existing requirements file, using the specs/_template/prd.template.md structure. - UI Wireframe Exploration: For features with UI, offers 2-3 low-fidelity wireframe options via the design skill, persists the .dc.html sources under specs/<slug>/wireframes/, and records design-system decisions in docs/DESIGN-SYSTEM.md. - Pipeline Governance: Assigns sequential spec numbers, logs invocation duration to timing-log.md, relays subagent questions to the user, and iterates on feedback until explicit approval. - Use Case: Describe a new dashboard feature in plain language; the Skill asks about wireframes, generates the PRD, summarizes it for approval, and hands off to the /btt-sdd:trd stage. ## Quick Start Ask the assistant to create a PRD for the new feature you want to build, optionally pointing to an existing requirements file.
